mech_spnego - Simple and Protected GSS-API Negotiation Mechanism
SYNOPSIS
/usr/lib/gss/mech_spnego.so.1
DESCRIPTION
The SPNEGO security mechanism for GSS-API allows GSS-API applications to negotiate the
actual security mechanism to be used in the GSS-API session. mech_spnego.so.1 is a shared
object module that is dynamically opened by applications that specify the SPNEGO Object
Identifier (OID) in calls to the GSS-API functions (see libgss(3LIB)).
SPNEGO is described by IETF RFC 2478 and is intended to be used in environments where mul-
tiple GSS-API mechanisms are available to the client or server and neither side knows what
mechanisms are supported by the other.
When SPNEGO is used, it selects the list of mechanisms to advertise by reading the GSS
mechanism configuration file, /etc/gss/mech (see mech(4)), and by listing all active mech-
anisms except for itself.
OPTIONS
SPNEGO may be configured to function in two ways. The first way is to interoperate with
Microsoft SSPI clients and servers that use the Microsoft "Negotiate" method, which is
also based on SPNEGO. The Microsoft "Negotiate" mechanism does not strictly follow the
IETF RFC. Therefore, use special handling in order to enable full interoperability. In
order to interoperate, place option "[ msinterop ]" at the end of the SPNEGO line in
/etc/gss/mech.
This is an example (from /etc/gss/mech):
spnego 1.3.6.1.5.5.2 mech_spnego.so [ msinterop ]
Without the "[ msinterop ]" option, mech_spnego will follow the strict IETF RFC 2478 spec-
ification and will not be able to negotiate with Microsoft applications that try to use
the SSPI "Negotiate" mechanism.
INTERFACES
mech_spnego.so.1 has no public interfaces. It is only activated and used through the GSS-
API interface provided by libgss.so.1 (see libgss(3LIB)).
